South Korea Voice Features and Restrictions


CLI

Local Korean numbers cannot be used as the CLI to send traffic towards South Korea.

You cannot add a plus sign (+) to CLI.

When calling from overseas, callers should see the international telephony carrier’s prefix and calling number, for example, if US number 14155551212 is calling a South Korean number, CLI added with a prefix shows up as 006 14155551212.

Prefixes for different carriers:

  • KT 001
  • LGU 002
  • SK Telink 006
